The future of WiFi
When the 11ac standard was published in 2013, it introduced new features including beamforming and MU-MIMO and changed the face of Internet service. However, 11ac only applied to the 5 GHz band. Service providers currently face increasing pressure from their subscribers as they adopt new applications which require much higher throughput speeds and simultaneous connections to multiple devices. The 11ac Wave 2 technology is unable to fulfill the growing bandwidth requirements of these advanced applications.
Meeting the ever-increasing demands for high-performance WiFi is a new technology, 802.11ax (11ax), which is also known as WiFi 6. 11ax features 1024-QAM which provides high-throughput in both 2.4 GHz and 5 GHz band, and supports MU-MIMO & Orthogonal Frequency Division Multiple Access (OFDMA) to improve the channel capacity and efficiency for enabling more clients to access the AP. Network functionality is improved by the Target Wake-up Time (TWT) and Basic Service Set (BSS) Color Code features.
The newest modulation standard with each coding symbol containing more bytes of data than 256-QAM, resulting in a 25% data rate increase.
10 Gbps WiFi Capability
11ax dual-band (2.4 GHz + 5 GHz) technology helps you overcome the limitations of single while maximizing each band’s merits. Used in combination with the 1024-QAM, it increases maximum physical (PHY) data transfer speeds to 10 Gbps.
When compared to the previous standard, 11ax offers MU-MIMO support both in the downlink and the uplink direction, allowing client data transmissions to be simultaneously received by the AP.
The OFDMA feature allows the AP to assign different parts of the spectrum to different users, improving traffic coordination and rational spectrum usage.
Resource Unit Scheduling
Rationalizing transmission channel usage by allocating and scheduling the resource units allows transmission channels to be reused.
BSS reduces interference between same-channel APs by adding channel color information, increasing network capacity and stability.
Target Wake-up Time
The AP coordinates transmission times from different sources, allowing devices to sleep during the non-transmission periods since there is no need to be awake and monitor beacons sent by the AP.
